Maybe.It depends on what and how much they make fun of you!If it relly pisses you of then i wood but tell her why.Or make a plan on how to stop making the people laugh and make fun of uu.Like saying to other people "NO!i dont like her anymore!"Then tell the other people to come with them to your girfriend and tell your girlfriend to say "I DONT LIKE HIM EITHER".then later u guys can hang out and stuff!THERE!I hope thats enough!BYE
